Porosity and Permeabiltiy

The Effect of Depleting our Groundwater Supply

A lot of pumping can lower the groundwater table, and cause wells to no longer be able to reach groundwater. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can no longer have the amount of water it needs.

Excessive pumping in coastal areas can cause saltwater to move inland and upward. This can resulting in saltwater contamination of the water supply.

Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, causing the soil to collapse, compact, and drop.

Over 50% of the United States population depends on groundwater. Because man-made materials-gasoline, oil, road salts and chemicals- get into the groundwater, it causes it to become unsafe and unfit for human use.

California is a good example of this. Some part is experiencing snow storms, flooding, and droughts. . One reason is because it's population is so large.
